This is nothing out of the ordinary for her. She bought a lot of clothes in Paris on the Reflection tour last year and her mom wrote a Facebook post about how she donated almost every piece of it to a homeless shelter there.
Dinah has always been about giving back and interacting with fans, which is why she's always had a place in my heart since her audition.

She may talk out of her ass sometimes but she has a heart of gold and people seem to dismiss that a lot. She's the nicest person.
